Vessel's Name. Here is the name of the vessel, and
immediately underneath is found any other name she may

is also shown), thus giving a continuous history of the ship.

Navigational Aids. Particulars are given of any naviga-

COLUMN (4)

Contains the name of the registered owner(s) of the ship.
This, may be—as is often the case—the name of the
managing owner. Also shown in this column are the
managers (if any), flag, and port of registry. The port of
registry may be any port at which the owners may desire
to register their vessel, and the flag shows the nationality
of the ship.

COLUMN (5)

Contains classification particulars. Classification may
be well described as the comparison with an ideal standard.
The class 100 Ai is defined in the Rules of Lloyd's Register
in the following words—

This character will be assigned to all seagoing ships built in
accordance with, or by standards equivalent to, the Society's Rules
and Regulations and the scantlings, arrangements and equipment
given in the Construction Rules for the draught required.

The equivalent British Corporation class, recorded in the
Register Book since the unification of the two Societies in
1949, is BS.
